E3 Intro Proteins Flashcards
Proteins lacking in serum
5 8 fibrinogen
Serum vs plasma
Serum is what remains after blood clots (red top)
Plasma is the fluid remaining when blood is prevented from clotting
Horses and exotics hepranized (prevents clotting) plasma used for serum biochem because naturally takes so long to clot
Three main plasma proteins
Albumin
Globulins
Fibrinogen
(+other)
Where are most plasma proteins sxn?
Liver
Where are immunoglobulins sxn?
Lymphoid organs
Plasma proteins in greyhounds
Usually lower than other dogs
own reference intervals
Major protein contributing to colloid osmotic pressure (COP)
Albumin (80%)
Globulins 20%
Protein measurement methods
Refractometer (Physical)
Spectrophotometer (biochemical)
Electrophoresis (Fractionation)
Causes of increased fibrinogen
Active inflammation (esp LA) Physiologic stress
Causes of decreased fibrinogen
DIC
Other: Snake bites/liver failure
Best way to analyze exotic species protein
Electrophoresis
Protein and RBC concentration with external hemmorag
Acute may be normal then fluid rapidly replaced causes
HYPOProteinemia and anemia
Protein and RBC concentration with dehydration
Relative hyperproteinemia and erythrocytosis
General Mechanism of hypoproteinemia
Decreased production
Increased loss
Sequestration
Dilution
General mechanisms of Hyperproteinemia
Hemoconcentration
Hyperglobulinemia
